To all whom it may concern Be it known that I HENRY Smmx, a citizen of the United tates, and resident of New York, in thecounty of New York and State of New York, have invented certain new and useful Improvements in MatcoHead or Similar Compositions, of which the followin is a specification My invention re ates to compositions for matches, fuses, and the like. 7

The object of my invention is to make match head compositions which are substantially damp-proof. This I accomplish Pateuted June 22 1315i hpplloution mm some 17, 1915. Serial m; 3,072.

pounds of potassium chlorate or sodium chlorate, pounds of oxid of zinc, l8

, pounds of phosphorus sesquisulfid or R1110!"- by substituting gum ammoniac for part of the glue or other binder, customarily used for the manufacture of match heads. suitable proportion of gum aromouiac lie 30% 1) Weight of the glue which would noimni y be used, omitting of course a corresponding ierceutage of giueg i. a. the binder woui be used in the proportion 01'- v dinarily used for such compositions, but

would consist of gum armnoniac 30% and glue 70%. The gum imuuoniac may be dissolved or emulsified in. Water before mixing with the glue.

My composition 'muy be manufactured for example in tho foliowing manner: In pounds of water are mixed 6 pounds of gum ammoniac, 1 2' pounds of glue or other agglutinatihg material, the solution or emulsion being promoted by heat ifnecessary. To this hinder there is added 40 phous'phosphorus and 20 pounds of pow dered glass or other filler. This mixture is used for making match heads in the cus tomery manner. the proportions may be varied and that i may use with my new hinder other mate ria suitable for the purpose sp wifieol. The matches thus produced I find to be sub-- stantially damp-proof.

I claim: 7 I

1. A composition of nutter for making match heads or other similar purposes, comprising combustible and iiflfl'liflg materials, ah oxygen carrying nmteriei and a binder containing gun) ammoniao, substantieily as described.

2. A composition of matter for making niotch heads and for simiiai purposes; comprising potassium chlorate, sulfid of phosphorus and a binder comprising es; aqueous paste of 30% of gum ammonia; and 70% of Iue. I
